If you get the 2wq subs then you are technically bi-amping the speakers because the subs contain a 300 watt amp within. Maybe that's what you're refering to.Even without the subs the Vandy's are a terrific sounding speaker and that includes all models.I've owned the 1b's,2cesig's and now have the 3a sig's and willl be getting 2 wq subs in a few weeks.The 2 subs give you about 75% of theModel 5's performance according to Richard V.(who I 've spoken to a few times)
If you ever want a mind blowing audio experience go listen to the Model 5's properly set up with Cary or Audio Research tube electronic,and vinyl ...you won't believe how great it sounds!
